COMB FOR TREATIN G THE SCALP Willy Jaber'g, Zurich, Switzerland Application October 7, 1953, Serial No. 384,563

Claims priority, application Switzerland October 8, 1952 3 Claims. (Cl. 132-115) The treatment of the scalp with liquids or ointments is rendered diicult owing to the fact that the liquid or ointment cannot be brought on to the scalp through the hair but is wholly or for the larger part intercepted or absorbed by the hair. This drawback has a disadvantageous effect especially in home treatment, in the case of which no other expedient is available, and, apart from insuicient treatment of the scalp, it causes a disproportionately large consumption of liquids or ointments with which the scalp is to be treated. This drawback is obviated by the present invention.

The subject matter of the present invention is a comb for treating the scalp, the teeth of which are provided with bores which pass through them longitudinally andv ink each of which there is provided a valve which is kept closed by spring action and the valve cone of which is provided` with a pin for opening the valve, which pin projects frornthe tip of the tooth and passes through the bore with clearance, a container for the substance intended for the treatment of the scalp being arranged on the back part of the comb.

Since, on using this comb, the liquid or ointment` intended for the treatment of the scalp issues at the tipsof the teeth, which slide on the scalp, the liquid or ointment isapplied to the scalp directly.

An example of embodiment of the subject matter of the invention is represented by the accompanying drawings, of which Eig. 1` is a longitudinal medial section through a comb for treating the scalp, and shows a device which may optionally be used for applying pressure to material within the comb;

Fig. 2 is an edge elevation of this comb;

Figs. 3 and 4 are two side elevations; and

Fig. 5 is a plan of a detail.

The comb represented for treating the scalp has a back part 1 of vulcanite, synthetic plastic or the like which is tted with teeth 2 on the side opposite the back. Provided in the back part 1 and in the teeth 2 are bores 3 which pass longitudinally through the teeth and which have a wider part 4 towards the back. The shoulders 5 between the wider parts 4 and the narrower bores 3 which open at the tips of the teeth are covered with packing rings 6, each of which is held by a sleeve 8 which is provided with a screw-threaded head 7 and which is screwed into an internal screw-thread of the wider part 4 of the bore 3. Arranged in each of these sleeves 8 is a second sleeve 9 which has, on its end that is directed towards the tip of the tooth 2, a valve cone 10 which co-operates with the packing ring 6 which serves as a valve seating and which has a conical recess for this purpose. Pressed tightly into the sleeve 9 is a pin 11 of vulcanite or the like, the front part of which passes through the narrow part or the bore 3 and projects beyond the tip of the tooth 2. A clearance of 0.1 to 0.2 mm. is left between the inside of this narrow part of tht bore 3 and pin 11 this; clearance is shown enlarged in Fig. 1 for the sake of clearness. The screw-threaded head 7 has a cross-bar 12 in which a guiding aperture 13 (Fig. 5) for the back part of the pin 11 is provided. Inserted into the sleeve S is a compression spring 14 which rests against the cross-bar 12 and presses the valve cone 10 on to -the packing ring 6 which acts as a valve seating. The sleeve 9 is shorter than the sleeve 8 and, when the valve cene 1d rests on the packing ring 5", the distance of the end of the sleeve 9 from the cross-bar 12 is somewhat smaller than the length of the part of the pin 11 that is projecting beyond the tip of the tooth 2. Fitted tightly on the back part 1, which has a shoulder 15, is a flat casing 16 which is provided with a filling opening lthat is closable by means of a closing screw 17.v Thisl casing 16 forms the container for the substance with -which the scalp is to be treated` For treating the scalp, the comb is passed through the hair, precisely as when it is being combed, and is pressed lightly on to the head. When this is being done, the ends of the pins 11 that project from the teeth 2 are pressed back into these teeth; the result of :this is that the sleeves 9, which rest firmly on the pins 11, are displaced inthe sleeves 8 towards the back of the comb and the valve cones 10 are raised from the packing. rings 6 that act as valve seatings. The substance which is contained in the casing 16 and with which the scalp is to be treatedl can now ow through the sleeves 8- and the interspaces between the pinsV 11 and the inside of the bores 3 in the teeth 2 directly on to the scalp: and act thereon without being hindered by the hair.

Owing. to the aforesaid dimensioning of the lengthv` of the sleeves 9, the pins 11 cannot be pushed back cornpletely into the teeth 2 but only to such an extent that thesleeve 9 strikes the cross-bar 12 of the sleeve 8, so that dandruii' or other foreign matter cannot enter the bores 3 and clog them.

1f a liquid is employed for treating the scalp, then, on pressing the comb on to the head, the liquid' flows automatically through the sleeves 8 andv the bores 3 on to the scalp. lf required, by pressingy together the broad sides of the casing 16, which is made of sheet metal or a suitable, elastic synthetic plastic, a pumping action, whichy promotes the discharge of the liquid from the bores 3, can be obtained. lf the scalpis to be treated with an ointment, a rubber bulb 18 or other suitable device is advantageously connected to the casing 16 for the purpose of applying pressure to the ointment in the casing 16 and forcing it out through the sleeves 8 and the bores 3.

I claim:

l. A comb for treating the scalp, comprising teeth provided with bores passing through them longitudinally, a valve in each of said teeth, spring means for keeping said valve closed, said valve having a valve cone, said valve cone having a pin for lifting said valve cone from the valve seating and thus opening said valve and said pin projecting from the tip of said tooth and passing through its bore with clearance, each said bore having a wider part towards the back part of the comb, a packing ring on the shoulder terminating said wider part, a first sleeve inserted in said wider part and holding said packing ring in position on said shoulder, a second sleeve arranged in said first sleeve and having said valve cone on its end that is directed towards the tip of the tooth, said spring means being in the form of a compression spring and arranged in said iirst sleeve and said pin being tightly pressed into said second sleeve, a container for the substance intended for the treatment of the scalp, said container being arranged on the back part of the comb and consisting of a casing fitted tightly on the back part of the comb and provided with a filling opening and the interior of said container and said irst sleeve being in communication, and a device connected to said filling opening for the purpose of applying pressure to the substance in said container.
